It was never made available in-game. While the item was fully-functional on the disc, it could never be obtained and was eventually removed in Version 2.3.0.
The Shirtstravaganza was a long-sleeved button-front shirt in a pale blue. It was covered in small, dark blue shirts in a polka-dot pattern, and had red buttons.
The Shirtstravaganza comes with Bomb Range Up as the primary ability. As a 1-star item, the Shirtstravaganza comes with one additional slot for secondary abilities, which may be increased to a maximum of three slots with a Super Sea Snail or 30,000 cash for each slot. Since it is made by the Splash Mob brand, it has a higher chance of rolling Ink Saver (Main) and a lower chance of rolling Run Speed Up to fill its secondary ability slot.
- Shirtstravaganza is a portmanteau of 'shirt' and 'extravaganza'.
- Although the Shirtstravaganza was never available to players, it appeared in a Sunken Scroll and various promotional images depict Inklings wearing it.
- This item was apparently superseded by Baby-Jelly Shirt, which is remarkably similar in appearance and is also made by Splash Mob.
- A UI icon for this item was discovered in the data files for Super Mario Maker. This variation is slightly brighter than the Splatoon variation.
